SPECIFICATION forming part Of Letters Patent No. 623,451, dated April18, 1899.

Application filed November 5, 1897. Serial No. 657,579. (No model.)

To (LZZ whom it may concern: 7

Be it known that LOORALNOVELLO Wnsr- WOOD,of Nanaimo,l3ritishOolnmbia,Canada, have invented a new and useful Improvement inType-lVriterAttachments, of which the following is a specification.

It is the object of this invention to provide improved means forcolumn-spacing, linespacing, and back spacing in type-writing, say, onmachines of the Remington andGaligraph type. The invention is embodiedin mechanism attached to the right-hand side of such a machine and whichis so connected with the rotary cylindrical platen and its reciprocatorycarriage as to adjust one or both, as required, for effecting eithercolumn, line, or back spacin The construction, arrangement, andoperation of such mechanism are hereinafter described,and shownintheaccompanying drawings, (three sheets,) in which Figure 1 is an end viewshowing my improved attachment applied to a Oaligraph type-writingmachine. Fig. 2 is a side or face view of the same. Fig. 3 is anenlarged horizontal section, on line 3 3 of Fig. 2, of'a portion of theattachment. Fig. 1 is a vertical section on line 4 4 of Fig. 3. Fig. 5,Sheet 2, is a rear elevation of the attachment applied to a Oaligraphmachine. Fig. 6 is an enlarged face view of a portion of the apparatus,part being broken away. Fig. 7 is a detail section of parts shown inFig. 6. Fig. 8, Sheet 3, is a plan view of the attachment. Figs. 9 and10 are plan and side views illustrating the treadle mechanism. Fig. 11is an enlarged longitudinal section of the platen and some of itsattachments.

I will first describe the means for releasing the platen and allowing itto run forward and stop it at certain points.

A cylinder 1 (see Figs. 1, 2, and 8) is secured by screws to the frontand right-hand side of the type-writer frame 2. In the vertical face ofsaid cylinder 1 a series of push-keys 3 are arranged in a circle to workin horizontal guides, their enlarged heads bearing numerals 5, 1O, 15,and other multiples of live corresponding to numbers inscribed on thescale or gage plate 2, Fig. 2, ordinarily used on typeavriting machines.The heads of these keys 3 are adapted to bear upon the outer ends of aseries of levers 4, Fig. 3, ar-

ranged radially on the face of the cylinder 1, with their convergentinner ends engaging jam-nuts 5, applied to a shaft 6. The levers arepivotedon a wire extending around a circular flange. The shaft 6 passestransversely through the cylinder 1 and across the end of thetype-writer frame 2 and is further supported horizontally by a bearingon the latter, as shown best in Fig. 1. On the rear end of the shaft 6are mounted a drum 13 and ratchet-disks 8 9, which will be hereinafterdescribed in detail. The shaft 6 is slidable longitudinally and alsorotatable. It is slid forward by depression of a key or push-pin 3,which thereby tilts a lever/l, which in turn acts on the jam-nuts, asshown by dotted lines, Fig. 3. The object of this movement of the shaft6 is to momentarily release the ratchet-disks 8 9 from engagement with apawl 10, Fig. 5. The pawl proper is pivotally attached to a vertical armor standard 10, that forms a fiXed attachment of the rocking bar orframe 11 usually employed on typewriters of the class hereinbeforereferred to. Consequently the pawl 10 oscillates laterally with said bar11 as the'latter rocks, and it is provided with a plate-spring 12 forholding it normally engaged with the ratchet-disks S and 9.

The drum 13,Fig. 1, is secured on shaft 6 and has lateral flanges,asshown. The ratchet-disk 9,Fig. 6. is secured ad justablyto the outersideof the drum 13 by means of screws 14, that pass through arc slots 15.The object of this adjustment of the disk 9 is to enable it to be set.

circumferentially, whereby to coincide with the ratchet-disk 8 and formpart of the mechanism for moving the carriage forward step by step,whichmechanisml shall now describe. It

will be understood that said disk is normally fast or fixed on the drum13 when in use. The other disk 8 is, however, loosely mounted on theshaft 6, but its circumferential movement is limited by screws passingthrough are slots 17 and entering shouldered studs or the spring 19normally holds the outer diskS IOO in the position shown in Fig. 6, inwhich its teeth register or coincide with those of the inner disk 9, sothat the pawl may slide laterally from one disk to the other whenoscillated by the rocking bar 11, as before stated. In furtherexplanation of this part of the attachment I will state that when thepawl 10 is cantedor moved inwardly it is carried from the loose ratchetS into engagement with the fixed ratchet 9, and the former, 8, beingthus left free is rotated and carried forward one notch or tooth by thetension of spiral spring 19. On rel urn of pawl 10 to its normalposition in contact with the loose ratchet 8 the platen-frame is allowedto move forward one space by means of the arc slots 17 in ratchet 3.Thus the movement of the pawl 10, as described, allows for a letter orletter-space in the writing done by the ma chine. \Vhen the shaft 6 isdrawn forward by a push-key 3 and lever 4, as before described, theloose disk 8 may be freed from the pawl 10. A cordor suitable wire cable20, Fig. 5, is secured at one end to the drum 13 and at the other to theplaten-frame 21, passing intermediately over an idle pulley 22 andthrough a guide 23, whereby it will be seen that the shaft 6 is rotatedwhen the platform 21 is slid. A binding-screw serves to secure the cableto platen-frame and as a means for taking up slack when required. Thiscable is provided with a spring attachment 24, preferably formed of aspiral spring arranged between two disks that slide on rods to which therespective divided portions of the cable 20 are attached. The functionof the spring 24is to to relieve shock on the cable 20 when operatingthe. platen that is to say, when the movement of 'the platen is checked.It will be understood that the function of the pull cord or cable 20 isto produce forward and backward movement- 1'. e., reciprocation of theplaten.

Returning now to Fig. 3, it will be seen that the shaft 6 has a radialarm 26, which is fixed thereon, and hence moves with it. When a key 3ispushed in, it projects into the rotary path of this arm, and thereforeserves as a stop for limiting the rotation of said shaft. A pull-cord 27is applied to the drum 13 and Winds thereon in a direction opposite thecable 20. This pull-cord is connected with a treadle, as hereinafterdescribed.

The following-stated conjoint operation of the parts before describedwill now be comprehensible. Say it is desired to allow the platen to runforward (or to the left) until the pointer, Fig. 2, is opposite thenumeral on the scale-bar 2, it being assumed the platen has been drawnback to the right-hand position shown in said figure. The operatorpresses inward that one of keys 3 whose head bears said numeral, andthus tilts the connected lever 4, which in turn acts against thejam-nuts 5 and draws the shaft 6 forward, together with itsattachmentsnamely, the arm 26, drum 13, and ratchet-disks 8 and 9,

' which latter are thus freed from the pawl 10.

Then the shaft 6 is free to rotate, so that the platen 25 and itscarriage 21 move forward or to the left until the arm 26 of shaft 6 inthe course of its rotation strikes the key 50, (which is still helddepressed by the operator) and thus the platen'carriage is stopped withthe pointer at 5O on the scale. If now the key 3 be released, the shaft6 will slide back to its normal position, being retracted by the spring28, which acts against a collar on said shaft, and the pawl 10 will thenrengage the outer ratchet 8, as before. The operator may return theplaten 25 to the former starting position by pressing the treadl'e so asto pull the cord 27, whereby the drum 13 is rotated and the cable 20wound on the same, which applies to the platen-carriage the forcenecessary to'move it to the right.

I will now describe the means for moving the platen 25 backward to apoint in any space intermediate the numeral 5 and its multiples. Asshown best in Figs. 3 and 4, a leverarm 30 is mounted loose on the shaft6 and projects through a lateral slot in the cylinder. It is heldnormally at the top of said slot by a wire spring 31, suitably connectedwith it and the cylinder. A ratchet-disk 32 is fastened by a set-screwon the shaft 6, and a pawl 33 is pivoted to said lever and adapted toengage it, as shown in Fig. 4. A stud or pin 34 holds the pawl out ofengagement when the lever 30 is raised; but when the latter is depressedthe spring 35, which bears on the heel of the pawl 33, throws its pointinward, and thus the ratchet 32 and shaft 6 are rota ted. It is apparentthis will also rotate the drum 13 and wind on the cable 20, whereby theplaten-carriage will be drawn to the right. Thus back spacing may beeffectedthat is to say, suppose the platen to have been adjusted to thenumeral 50, as before, and it be desired to move it back to 48 the lever30 is twice depressed in order to rotate the ratchetdisk 32 the distanceequivalent to two spaces or notches on the latter. In other words, thedownward throw of the lever 30 turns the shaft 6 and drum 13 backward,and thereby pulls on the cable 20, which in turns draws theplaten-carriage back one space.

I will now describe the means for effecting line-spacing, which iseffected, as usual, by rotating the platen 25 the required distance. Theplaten is mounted slidably, but not rotatably, on a shaft 36, Fig. 8,having a ratchetdisk 37 fixed on its right-hand end, to which disk arotative step-bystep motion is imparted by a lever 38 and spring-pawl 39through the medium of a pull-cord 40, connected with a treadle, as willbe hereinafter described. The shaft 36 does not slide, but

grooved throughout its length and afeather It, Fig. 11, attached to theextended hub 45 of the platen enters and slides in such groove. A sleeve-16 is interposed between the shaft 36 and hub .5 to take the frictionand wear.

It will be apparent that if the operator moves the treadle so as to pullthe cord 4:0 the lever 38 will be depressed and its pawl 39 caused toengage the ratchet 37, thereby tu rning the shaft 36 and platen 25together, so that the lat terisadjusted as required for linespacing. Thelever 38 is thrown up to its normal position by a spring 46, Fig. l. Thesaid lever works in a keeper attached to bracket-flange ti.

I propose to employ any suitable treadle mechanism to operate thepull-cords 27 and 40. In Figs. 0 and 10 I show two treadles that may beadvantageously employed. The pull-cords pass down through the table a7and over idle pulleys 48 to lateral arms 49 of the respective treadlesproper. Each of these latter is formed of a vertical shaft 50, set atits end on pivots attached, respectively, to the table and floor andprovided with lateral footrests 51. Spiral springs are attached to thehead of each post or shaft 50 for throwing it back to normal position.By applying a foot to each rest 51 the operator may rotate the shafts,and thus cause their arms 49 to pull the cords 27 40 when required toreturn the platen-carriage or to rotate the platen for spacing betweenthe lines. The dotted lines, Fig. 9, illustrate the movements of thetreadle mechanism so far as requisite to enable the operation to beunderstood. lVhen the platen has been returned by operating a treadle topull-cord 27, its arm 'or check 52, Figs. 2 and 8, strikes a rubberbuffer 53, attached to the machine-frame 2 by means of asupportingbracket 5%.

Recapitulating, spacing between the lines is effected by a treadlemechanism operating through the pull-cord 40 on the lever 38 and ratchet37, whereby the shaft 86 and platen 25 are rotated. The operation of theother treadle draws the platen back to starting position, and the handor thumb lever 30, ratchet 37, and shaft 36 serve to bring the platenback one or two spaces.
